If the network connection to nntp sites is temporarily down when nntpcached (version 1.0) is started, it will exit with a SIGSEGV. Is this intentional? Is it possible and/or desirable to introduce a more graceful behavior for this situation? I've also done some exploring in the rfc931 code in acc.c, which as I noted earlier does not work on Sunos. The following simple change fixes it. (Sunos requires separate read/write files for the socket -- dunno why.) cd /usr/local/src/nntpcache-1.0/ diff -c /usr/local/src/nntpcache-1.0/acc.c.orig /usr/local/src/nntpcache-1.0/acc.c *** /usr/local/src/nntpcache-1.0/acc.c.orig Tue Oct 15 13:00:57 1996 --- /usr/local/src/nntpcache-1.0/acc.c Tue Oct 22 12:45:23 1996 *************** *** 28,33 **** --- 28,37 ---- static char user[128]; char buf[512]; FILE *fh = NULL; /* stop gcc complaining */ + /* ron@auda.mlfarm.com, 22 Oct 1996 */ + /* For Sunos we need separate */ + /* read/write FILEs. */ + FILE *fr = NULL; RETSIGTYPE (*al)(int) = NULL; long al_s; *************** *** 48,58 **** } if (connect (sock, (struct sockaddr *) &remote_query_sin, sizeof (remote_query_sin)) == -1) goto err; ! fh = fdopen (sock, "r+"); fprintf (fh, "%u,%u\r\n", ntohs (remote_sin->sin_port), ntohs (our_sin->sin_port)); fflush (fh); ! if (fgets (buf, sizeof buf, fh) ! && !ferror (fh) && sscanf (buf, "%u , %u : USERID :%*[^:]:%127s", &remote_port, &our_port, user) == 3 && ntohs (remote_sin->sin_port) == remote_port && ntohs (our_sin->sin_port) == our_port) --- 52,65 ---- } if (connect (sock, (struct sockaddr *) &remote_query_sin, sizeof (remote_query_sin)) == -1) goto err; ! /* ron@auda.mlfarm.com, 22 Oct 1996 */ ! /* Sunos needs separate read/write FILEs */ ! fh = fdopen (sock, "w"); ! fr = fdopen (sock, "r"); fprintf (fh, "%u,%u\r\n", ntohs (remote_sin->sin_port), ntohs (our_sin->sin_port)); fflush (fh); ! if (fgets (buf, sizeof buf, fr) ! && !ferror (fr) && sscanf (buf, "%u , %u : USERID :%*[^:]:%127s", &remote_port, &our_port, user) == 3 && ntohs (remote_sin->sin_port) == remote_port && ntohs (our_sin->sin_port) == our_port) -- Ronald Florence Maple Lawn Farm, Stonington, CT ron@mlfarm.com http://www.connix.com/~mlfarm
